——再生聚苯硫醚应用、等级、性能与颜色全参考（含2026-09-11报价单样本数据）
1 概述
1.1 什么是再生PPS
PPS（Polyphenylene Sulfide，聚苯硫醚）是一类半结晶性特种工程塑料，工业上多采用Macallum法由对二氯苯与硫化钠在NMP溶剂中缩聚得到（FDA 21 CFR 177.2490 对PPS树脂的食品接触用途有明确界定）。纯PPS熔点约280℃，密度1.34–1.36 g/cm³，GF40增强级约1.63–1.66 g/cm³；长期使用温度200–240℃，1.82MPa下热变形温度260–280℃；PPS具有本征阻燃性，UL94 V-0级无需添加阻燃剂即可在0.4mm壁厚下通过；200℃以下几乎不被常见有机溶剂溶解，耐无机酸、碱、盐腐蚀。
再生PPS（rPPS）按料源可分为两类：PIR（Post-Industrial Recycling）来自注塑水口料、流道、浇口和生产不合格品；PCR/工业来源来自汽车电子拆解（传感器、连接器、热管理部件）、电子电器拆解（继电器、线圈骨架、接插件）、工业泵阀衬里以及PPS纤维除尘滤袋。典型回收工艺为：破碎（3–10mm）→ 分选/清洗 → 真空脱挥 + 熔体过滤（滤材≤25μm）→ 270–320℃单/双螺杆造粒 → 改性复配。
行业通行掺混比例为回收料掺入10–25%时力学性能无明显损失；宝理DURAFIDE官方建议回收料比例不超过25%，部分等级可放宽至50%。100%回收料会因玻纤断裂、分子量下降而导致力学与耐热性能下降，并伴随明显变色。
1.2 核心价值
成本端：再生PPS主流成交价约1.15万–4.3万元/吨，原生改性PPS约3.8万–6万元/吨，再生料较原生低约30–50%。环保端：参照帝人（Teijin）等标杆企业机械回收口径，GHG减排约60–70%（行业标杆值，PPS专项LCA数据待补）；原生PPS因NMP溶剂路线、高温脱水缩聚和溶剂回收环节能耗较高，回收减排空间在工程塑料中属于较为突出的一档。
政策端：国家发展改革委等七部门《再生材料应用推广行动方案》（发改环资〔2025〕1681号，2025-12-23）是我国首个专门部署再生材料应用推广的政策文件，明确汽车内外饰件率先规模化应用再生塑料，电器电子产品非运动/结构件加大再生塑料应用；《中华人民共和国生态环境法典》于2026-08-15施行，废塑料首次写入国家法律，被定义为可回收资源。PPS虽暂未在配套比例条款中点名，但其在汽车热管理、电子连接器等高价值场景对政策方向具有较强跟随性。
2 应用领域与具体产品

3 行业等级体系
国家标准现状：GB/T 40006系列已发布.1通则、.2 PE、.3 PP、.5 ABS、.6 PS、.10 PBT、.11 PVC、.13 PPE等分部分；截至2026年9月，该系列尚无PPS专项分部分，再生PPS目前执行GB/T 40006.1-2021《通则》通用框架。原生PPS命名国标仍在制定中（TC15/SC9归口，中蓝晨光起草），尚处计划阶段。颜色代码沿用GB/T 40006.1通用体系（B黑/G灰/N本色/X杂色）。
行业通行分级主要从五个维度展开：按玻纤含量、按加工用途、按改性方向、按纯度品级、按牌号体系。详见表5。
表5 再生PPS行业等级体系总览
| 分级维度 | 具体等级 | 说明 |
|---|

4 性能指标
4.1 原生与再生对比
原生PPS/GF40的典型性能见表6；再生PPS因破碎+再熔融过程中玻纤平均长度下降、分子量降低，拉伸与弯曲强度较原生下降约15–30%，但熔点、阻燃等级与耐化学性主要由分子链结构决定，保留率较好。
表6 原生PPS/GF40典型性能指标
| 指标 | 单位 | 原生PPS/GF40典型值 | 数据来源 |
|---|
| 拉伸强度 | MPa | 165–200（未增强纯料65–83） | 找塑网/Kureha/yonei |

| MFI（260℃口径） | — | 50–200 g/10min | — |
| 掺混比例建议 | — | 10–25%掺混力学无明显损失；宝理建议≤25%，部分等级≤50% | — |
4.2 按玻纤含量与用途分级
玻纤含量决定刚性、耐热与成本；加工用途决定流动性与熔体强度要求。再生PPS选级时需同时对照两个维度，详见表8。
表8 再生PPS按玻纤含量与用途分级
| 分级方向 | 典型规格 | 性能/加工特点 | 典型应用 |
|---|
| 按玻纤含量 | GF20 | 韧性较好、密度较低、翘曲小 | 薄壁接插件、灯座 |
| 按玻纤含量 | GF30 | 平衡刚韧与流动性 | 继电器壳体、传感器支架 |
| 按玻纤含量 | GF40（主流） | 刚性/耐热/成本平衡 | 汽车连接器、水泵壳体、电子外壳 |
| 按玻纤含量 | GF45/GF60 | 高刚性、高耐热、高比重 | IGBT外壳、热交换器、结构件 |
| 按用途 | 注塑级 | 流动性好、成型周期短 | 电子电器、汽车结构件 |
| 按用途 | 挤出级 | 熔体强度高、流动性低 | 管道、板材、棒材 |
| 按用途 | 纤维级 | 纺丝级分子量与分子量分布控制 | 除尘滤袋、针刺过滤毡 |
| 按用途 | 涂料级 | 细粉/分散性好 | 不粘涂层、防腐涂层 |
5 颜色体系
再生PPS的颜色直接决定售价与定位。多次热历史（290–320℃再加工）会使本色→黄→棕→深褐/黑，热氧降解自然形成深色；深色料可掩盖杂质与配色偏差，浅色高品级则要求使用本白色PIR水口料并严格控制热历史，价格可达黑色料的2–3倍。
表9 再生PPS颜色体系（含2026-09-11报价单价格）
| 颜色 | 报价（元/吨，2026-09-11） | 品级定位 | 特点 |
|---|
| 黑色（普通） | 11,500 | 低端/一级 | 遮盖杂质、成本较低，主流大宗品种 |
| G0特级黑色 | 40,000 | 特级 | 高纯度黑色，品级溢价 |
| 深棕 | 21,000 | 中端/一级 | 热降解自然色，WR-4深棕 |
| 浅棕 | 21,800 | 中端/一级 | W3010浅棕，调色后使用 |
| 蓝色 | 22,000 | 中端/一级 | 调色料，兰色22,000元/吨 |
| 本白/本色 | 35,000 | 高端/特级 | 需本色PIR水口料，严控热历史 |
| 钛白 | 32,000 | 高端/特级 | WR-4-08钛白，高洁净浅色 |
| 大红 | 43,000 | 高端定制/特级 | WR-4-09大红色，报价单价格上限 |
| 锈铁红 | 35,000 | 高端定制/特级 | 染色调制，溢价高 |
为何再生PPS多为深色：①加工温度高（290–320℃），多次热历史导致热氧降解，颜色沿本色→黄→棕→深褐/黑演变；②100%回收料易引起变色（宝理官方说明）；③深色基体可掩盖杂质与配色偏差，降低分选成本。因此，本白、钛白、大红/锈铁红等浅色或高饱和色料均属高端定制，需要干净PIR料源与严格工艺控制。
6 市场与趋势速览
6.1 产能与价格格局
原生PPS产能格局（作对照）：新和成PPS年产能约2.2万吨，国内市占率居前、全球第三（东丽约3.36万吨、DIC约2.3万吨），2024年满产满销，是国内少数同时覆盖纤维/注塑/挤出/涂料四个级别的厂商；其他主要原生厂商包括雪佛龙菲利普Ryton（索尔维）、宝理DURAFIDE（DIC）、东丽Torelina、塞拉尼斯Fortron、四川得阳等。

6.3 应用结构、区域与政策
应用结构：按公开行业报告口径，PPS下游约为汽车38.6%、电子连接器29.1%、工业泵阀等32.3%（豆丁报告口径，待核实）。
区域分布：原生PPS产能集中在浙江（新和成，绍兴）与四川（得阳）；再生/改性产能集中在长三角（浙江、苏州）与珠三角（东莞、中山、佛山）。国内再生PPS产量尚无权威公开数据，定性判断为小众高值再生品种，规模远小于rPET/rPP/rABS，废料来源分散、单批次量小。
政策法规：中国方面，《再生材料应用推广行动方案》（发改环资〔2025〕1681号，2025-12-23七部门联合）为首个专门部署再生材料应用推广的政策文件；《生态环境法典》2026-08-15施行，废塑料首次入法；配套细则中2026年7月起大家电再生PP/ABS≥12%、新能源汽车结构件再生ABS/PETG≥8%（豆丁口径，待核实），PPS暂未被具体比例条款点名。
欧盟方面，ELV框架要求2032年再生材料≥15%、2036年≥25%；宝马2025年采购政策要求外饰塑料PCR≥30%并配套ISCC PLUS；奔驰Ambition 2039目标2030年新车100%可循环。再生PPS出口欧盟还需满足WEEE、RoHS 3.0、REACH SVHC筛查；PPS本身无禁用问题，再生来源须通过SVHC筛查。
日本方面，《资源有效利用促进法》推动容器包装与家电再生；东丽已推出PPS化学回收技术，机械强度接近原生；PPS在日本被定位为准贵重工程塑料，鼓励闭环回收。
减排数据：原生PPS碳足迹按豆丁口径约每吨成品4.8吨CO₂e（对照PTFE约9.2吨，报告口径待核实）。帝人（Teijin）机械回收宣称非增强级GHG减排约70%、增强级约60%（帝人自有口径，非PPS专属，为行业标杆企业通用工程塑料数据）。引用时建议表述为：参照帝人等标杆机械回收口径，GHG减排约60–70%（行业标杆值，待PPS专项LCA核实）。
6.4 东南亚进口渠道与料源背景
政策与贸易背景：中国2017年禁废令后，再生粒子采购与产能向越南、泰国、马来西亚、印尼、菲律宾转移。RCEP框架下超过90%的塑料产品实现零关税，东盟与中国90%以上产品互市零关税，凭原产地证即可享惠。泰国自2025年起全面禁止进口废塑料，倒逼本地回收产线升级；越南、马来西亚成为中资再生/改性产能主要承接地。
中资出海格局：越南方面，英科再生2019年建清化基地、2025年二期投产，大量中资改性/再生厂设厂；马来西亚方面，金发科技设马来子公司，依托东盟关税辐射汽车/家电/电子市场，兼具中美贸易缓冲中转功能，山东企业在马建有10万吨/年再生PS/PET粒子产能；泰国方面，泰国4.0战略鼓励汽车电动化与回收再生设备外资；印尼、菲律宾以中低端回收与初加工为主。
对再生PPS的含义：现阶段直接从东南亚规模化进口再生PPS的公开数据未见；更现实的渠道是中资改性厂在东南亚设厂后将再生改性粒子返销国内，享受RCEP零关税。东南亚渠道目前主要承载rPS/rPET/通用工程塑料再生料，特种PPS再生料的东南亚来源以定性描述为主，引用时不宜给出具体规模数字。

——Comprehensive Reference for Recycled Polyphenylene Sulfide Applications, Grades, Performance, and Colors (Including Quotation Sample Data as of 2026-09-11)
1 Overview
1.1 What is Recycled PPS
PPS (Polyphenylene Sulfide) is a type of semi-crystalline specialty engineering plastic. Industrially, it is mostly produced via the Macallum method by polymerizing p-dichlorobenzene with sodium sulfide in NMP solvent (FDA 21 CFR 177.2490 clearly defines the food contact applications of PPS resin). Pure PPS has a melting point of about 280°C and a density of 1.34–1.36 g/cm³, while GF40 reinforced grade has a density of about 1.63–1.66 g/cm³; the long-term use temperature is 200–240°C, and the heat deflection temperature under 1.82 MPa is 260–280°C. PPS has inherent flame retardancy and can pass UL94 V-0 at a wall thickness of 0.4mm without adding flame retardants. Below 200°C, it is almost insoluble in common organic solvents and is resistant to corrosion by inorganic acids, bases, and salts.
Recycled PPS (rPPS) can be divided into two types based on the material source: PIR (Post-Industrial Recycling) comes from injection molding sprues, runners, gates, and production rejects; PCR/industrial sources come from automotive electronics disassembly (sensors, connectors, thermal management components), electronic and electrical disassembly (relays, coil skeletons, connectors), industrial pump and valve linings, as well as PPS fiber dust filter bags. The typical recycling process is: crushing (3–10mm) → sorting/cleaning → vacuum devolatilization → melt filtration (filter ≤25μm) → 270–320°C single/double screw granulation → modification and blending.
The industry-standard blending ratio shows that when recycled material is added at 10–25%, there is no significant loss in mechanical performance; BASF's official recommendation for DURAFIDE is that the recycled material ratio should not exceed 25%, and for some grades, it can be relaxed to 50%. Using 100% recycled material will cause a decrease in mechanical and heat resistance performance due to glass fiber breakage and a reduction in molecular weight, accompanied by noticeable discoloration.
1.2 Core Values
Cost side: The mainstream transaction price of recycled PPS is about 11,500–43,000 yuan/ton, while that of virgin modified PPS is about 38,000–60,000 yuan/ton, with recycled material being approximately 30–50% cheaper than virgin material. Environmental side: Referring to mechanical recycling standards of benchmark companies like Teijin, GHG emissions can be reduced by about 60–70% (industry benchmark value, specific LCA data for PPS is to be added); due to the NMP solvent route, high-temperature dehydration polycondensation, and energy consumption in solvent recovery, virgin PPS has relatively high energy use, making the potential for emission reduction through recycling comparatively prominent among engineering plastics.
Policy side: The "Action Plan for the Promotion of Recycled Materials" issued by seven departments including the National Development and Reform Commission (NDRC Huanzi [2025] No. 1681, 2025-12-23) is China's first policy document specifically deploying the promotion of recycled material applications. It clearly states that automotive interior and exterior parts will take the lead in large-scale use of recycled plastics, and non-movement/structural parts of electrical and electronic products will increase the use of recycled plastics. The "Environmental Code of the People's Republic of China" came into effect on 2026-08-15, and waste plastics were included in national law for the first time, being defined as recyclable resources. Although PPS has not yet been specifically mentioned in supporting ratio provisions, its applications in high-value scenarios such as automotive thermal management and electronic connectors strongly follow policy directions.
2 Application Areas and Specific Products
According to publicly available industry reports, the downstream application structure of PPS is approximately 38.6% for automobiles, 29.1% for electronic connectors, and 32.3% for industrial pumps and valves (according to Douyin reports, to be verified). The table below classifies them into four major segments: automotive, electronics/electrical/communications, industrial machinery/chemical equipment, and environmental filtration & others, and highlights the core material selection characteristics of each segment.
2.1 Car
The automotive sector is a leading downstream segment in PPS global sales (according to some foreign manufacturers, it accounts for about 45%). The core material requirements are: long-term heat resistance up to 220°C, low dielectric loss, dimensional stability, resistance to antifreeze/fuel, and intrinsic UL94 V-0 flame retardancy; the new energy high-voltage platform imposes higher requirements on the CTI and flame retardancy of 800V/1000V connectors.

3 Industry Classification System
Current Status of National Standards: The GB/T 40006 series has been released, including Part 1 General Rules, Part 2 PE, Part 3 PP, Part 5 ABS, Part 6 PS, Part 10 PBT, Part 11 PVC, and Part 13 PPE. As of September 2026, there is no specific part for PPS in this series, and recycled PPS currently follows the general framework of GB/T 40006.1-2021 "General Rules." The national standard for naming virgin PPS is still under development (under the jurisdiction of TC15/SC9, drafted by Zhonglan Chenguang) and is still in the planning stage. Color codes continue to follow the general system of GB/T 40006.1 (B Black / G Gray / N Natural / X Mixed).
Industry-standard classification mainly unfolds across five dimensions: by glass fiber content, by processing purpose, by modification direction, by purity grade, and by grade system. See Table 5 for details.

4 Performance Indicators
4.1 Comparison of Native and Regenerated
The typical properties of virgin PPS/GF40 are shown in Table 6; recycled PPS experiences a reduction in the average fiber length and molecular weight during crushing and remelting, resulting in a decrease of about 15–30% in tensile and flexural strength compared to virgin material. However, the melting point, flame retardant rating, and chemical resistance are mainly determined by the molecular chain structure and are well retained.
Table 6 Typical Performance Indicators of Virgin PPS/GF40
| Indicator | unit | Typical Values of Virgin PPS/GF40 | Data Source |
|---|

| Recommended mixing ratio | — | 10–25% blending shows no significant loss in mechanical properties; Borealis recommends ≤25%, some grades ≤50% | — |
4.2 Classification by Glass Fiber Content and Use
The glass fiber content determines rigidity, heat resistance, and cost; the intended processing application determines the requirements for fluidity and melt strength. When grading recycled PPS, both dimensions need to be considered simultaneously, as detailed in Table 8.
Table 8 Classification of Recycled PPS by Glass Fiber Content and Application
| Classification Direction | Typical specifications | Performance/Processing Characteristics | Typical Applications |
|---|
| By glass fiber content | GF20 | Good toughness, low density, small warping | Thin-walled connectors, lamp holders |
| According to glass fiber content | GF30 | Balancing rigidity and flexibility | Relay housing, sensor bracket |
| By glass fiber content | GF40 (mainstream) | Rigidity/Heat Resistance/Cost Balance | Automotive connectors, water pump housings, electronic enclosures |
| According to glass fiber content | GF45/GF60 | High rigidity, high heat resistance, high specific gravity | IGBT housing, heat exchanger, structural components |
| By purpose | injection molding grade | Good liquidity, short molding cycle | Electronic and electrical appliances, automotive structural parts |
| By purpose | Extrusion grade | High melt strength, low flowability | Pipes, plates, and bars |
| By purpose | Fiber grade | Control of spinnable grade molecular weight and molecular weight distribution | Dust filter bags, needle-punched filter felt |
| By purpose | Coating grade | Fine powder / good dispersibility | Non-stick coating, anti-corrosion coating |
5 Color System
The color of regenerated PPS directly determines its price and positioning. Multiple heat histories (reprocessing at 290–320°C) will change the natural color → yellow → brown → dark brown/black, with thermal-oxidative degradation naturally forming darker colors; dark-colored material can mask impurities and color deviations, while light-colored high-grade material requires the use of natural white PIR sprue material and strict control of heat history, and its price can be 2–3 times that of black material.
Table 9 Recycled PPS Color System (Including Quotation Prices as of 2026-09-11)
| Color | Quotation (Yuan/ton, 2026-09-11) | Grade positioning | Characteristics |
|---|
| Black (Standard) | 11,500 | Low-end/Level 1 | Covers impurities, relatively low cost, mainstream bulk varieties |
| G0 Premium Black | 40,000 | Special grade | High-purity black, grade premium |
| Dark brown | 21,000 | Mid-range/Level 1 | Thermal degradation natural color, WR-4 dark brown |
| Light brown | 21,800 | Mid-range/Level 1 | W3010 Light Brown, use after mixing colors |
| Blue | 22,000 | Mid-range/Level 1 | Colorant, blue, 22,000 yuan/ton |
| Natural/Original color | 35,000 | High-end / Premium | Requires natural-colored PIR water inlet material, strictly control thermal history |
| Titanium White | 32,000 | High-end / Premium | WR-4-08 titanium dioxide, high purity light color |
| Bright red | 43,000 | High-end Custom / Premium | WR-4-09 bright red, maximum price on the quotation |
| Rust Red | 35,000 | High-end Custom / Premium | Color dye formulation, high premium |
Why recycled PPS is mostly dark: ① High processing temperatures (290–320℃) and multiple thermal histories lead to thermo-oxidative degradation, causing the color to evolve from the natural color → yellow → brown → dark brown/black; ② 100% recycled material can easily cause discoloration (according to Borealis official statement); ③ Dark-colored matrices can mask impurities and color deviations, reducing sorting costs. Therefore, off-white, titanium white, bright red/rust red, and other light or highly saturated colors are considered high-end custom colors, requiring clean PIR sources and strict process control.
6 Market and Trend Overview

6.3 Application Structure, Region, and Policy
Application structure: According to publicly available industry reports, the downstream of PPS is approximately 38.6% in automobiles, 29.1% in electronic connectors, and 32.3% in industrial pumps and valves (according to the Docin report, to be verified).
Regional distribution: Native PPS production capacity is concentrated in Zhejiang (Xinhoucheng, Shaoxing) and Sichuan (Deyang); recycled/modified production capacity is concentrated in the Yangtze River Delta (Zhejiang, Suzhou) and the Pearl River Delta (Dongguan, Zhongshan, Foshan). There is no authoritative public data on domestic recycled PPS production, but it is qualitatively judged to be a niche high-value recycled variety, with a scale far smaller than rPET/rPP/rABS, and the waste material sources are fragmented with small batch sizes.
Policies and Regulations: In China, the "Action Plan for the Promotion of Recycled Material Applications" (NDRC Environment and Resources [2025] No. 1681, joint issuance by seven departments on 2025-12-23) is the first policy document specifically deploying the promotion of recycled material applications. The "Codification of Environmental Law" will come into effect on 2026-08-15, marking the first inclusion of waste plastics into the law. In supporting regulations, starting from July 2026, recycled PP/ABS in major home appliances is required to be ≥12%, and recycled ABS/PETG in structural parts of new energy vehicles is required to be ≥8% (according to Dou Ding's figures, pending verification). PPS has not yet been mentioned in specific proportion clauses.
On the EU side, the ELV framework requires recycled materials to be ≥15% by 2032 and ≥25% by 2036; BMW's 2025 procurement policy requires exterior plastic PCR ≥30% and supporting ISCC PLUS certification; Mercedes-Benz's Ambition 2039 target aims for 100% recyclability of new cars by 2030. Recycled PPS exported to the EU must also comply with WEEE, RoHS 3.0, and REACH SVHC screening; PPS itself has no prohibited issues, but recycled sources must pass SVHC screening.
In Japan, the 'Resource Effective Utilization Promotion Law' promotes the recycling of container packaging and home appliances; Toray has launched PPS chemical recycling technology, with mechanical strength close to virgin material; PPS is positioned in Japan as a quasi-valuable engineering plastic, encouraging closed-loop recycling.
Emission Reduction Data: The carbon footprint of virgin PPS is approximately 4.8 tons of CO₂e per ton of finished product according to DouDing standards (compared to about 9.2 tons for PTFE, to be verified according to report standards). Teijin's mechanical recycling claims a non-reinforced GHG reduction of about 70% and a reinforced GHG reduction of about 60% (Teijin's own standards, not PPS-specific, for general engineering plastics as a benchmark in the industry). When quoting, it is recommended to state: according to Teijin and other benchmark mechanical recycling standards, GHG reduction is about 60–70% (industry benchmark value, to be verified by PPS-specific LCA).
6.4 Southeast Asia Import Channels and Material Source Background
Policy and Trade Background: After China's 2017 ban on waste, the procurement and production capacity of recycled pellets shifted to Vietnam, Thailand, Malaysia, Indonesia, and the Philippines. Under the RCEP framework, over 90% of plastic products achieve zero tariffs, and more than 90% of products traded between ASEAN and China enjoy zero tariffs with a certificate of origin. Thailand will completely ban the import of waste plastics from 2025, forcing local recycling production lines to upgrade; Vietnam and Malaysia have become the main destinations for Chinese-invested recycled/modified production capacity.
Chinese Overseas Investment Pattern: In Vietnam, Yingke Recycling built a base in Thanh Hoa in 2019 and launched the second phase in 2025, with many Chinese-funded modification/recycling plants setting up factories; in Malaysia, Kingfa Technology established a Malaysian subsidiary, leveraging ASEAN tariffs to reach the automotive/home appliance/electronics markets, while also serving as a buffer and transit function for China-US trade. Shandong companies have 100,000 tons/year of recycled PS/PET particle production capacity in Malaysia; in Thailand, the Thailand 4.0 strategy encourages foreign investment in automotive electrification and recycling equipment; in Indonesia and the Philippines, the focus is mainly on low- to mid-end recycling and initial processing.
Regarding the meaning of recycled PPS: Currently, there is no public data on large-scale direct imports of recycled PPS from Southeast Asia; a more realistic channel is that Chinese modification manufacturers set up plants in Southeast Asia and then sell the recycled modified pellets back to China, enjoying zero tariffs under RCEP. At present, Southeast Asian channels mainly handle rPS/rPET/general engineering plastic recycled materials. The sources of specialty PPS recycled materials in Southeast Asia are mainly described qualitatively, and specific scale numbers should not be provided when quoting.
